I've been doing some reading in the older threads and am trying to make sense of this. I have pretty much a rev hard style setup and am using aem (1052). I don't have any sort of a/f gauge at all in the car but it has been tuned on the dyno and running well.

I've read about burning up o2 sensors because the aem doesn't require them. My question is firstly, if I want to add a wideband, can I simply take out my primary o2 sensor (providing that this is no longer needed with aem ems) and plug in an aftermarket one such as the PLX and wire up the gauge independently of the ems?

Any insight or ideas would be greatly appreciated.

 

yes. You can wire the wideband into the EMS too.

 

you'll really want the AEM with the wideband built in, so much nicer. you can send a wideband signal from another wideband like the innovate one, but built is is better.

I've run an AEM in two different cars for about 3 years total, never had a problem with wideband sensors. my buddy has had his AEM for at least 3 years on his S and the sensor is fine.

 

1052U is sooooo much nicer. I have one in my car right now..

I have a wideband from AEM that can connect to the EMS also (it was used on an older 1012 unit) somewhere in my garage...

 

Hmmm...maybe for next Christmas I'll get a 1052U, but in the meantime, I'm stuck with this thing which is not that bad truth be told.

In any case, does using the regular 1052 make the factory o2 sensor obsolete?

 

Yes, factory o2 sensors are obsolete with the AEM EMS. You dont need to get the 1052U as you already have the 1052. Dont waste your money. Just get a PLX or Innovate WB and wire it in. I've had the Innovate XD-1 since 03 and its wired in and sinked up to the AEM and have had zero problems. A WB is also good to have so you can keep an eye on things occasionally. Plus you can data log pulls and driving and download it if something happens and it will show you if it was the A/F that was a problem. Also, having a WB sinked with the AEM all the time is good for o2 feedback on the AEM. This will adjust regular driving A/F's as things in the atmosphere change. In wide open throttle though, o2 feedback goes off and just runs off the wide open map that was tuned into the car.

 

That's sweet, I'll do that sooner than later. So essentially, I can buy a wideband sensor with gauge and simply plug in the o2 sensor for the wideband into the s2k's primary o2 sensor bung?

Also, can I use any wideband or am I limited to the 2 that you mentioned? Are these the only two that can sinc up to the aem 1052?

Finally, if I don't sinc up to the 1052, I can still run the wideband of my chosing independently of the aem entirely correct?

Thanks for the quick replies mate!

 

Yes, you can simply plug the o2 WB into the bung of the factory primary o2. Then get whatever WB o2 you prefer (it doesnt have to be one of the two I mentioned) and wire it into the factory primary o2 sensor wire under the dash. This will connect it to the AEM but you will have to sinc the WB to the AEM and select all the correct parameters in the AEM to get it to work. It's pretty simple if you know the AEM software.

Yes, if you hook up your WB to the wire I mentioned that goes to the AEM but havent done the software in the AEM yet to sinc everything up and what not, you will still see the correct A/F's on your external gauge regardless of what is going on in the AEM. The only reason to wire it into the AEM through the factory primary wire, sinc it in and set up all the parameters is to have the ability to datalog everything and setup o2 feedback for the AEM to adjust the A/F during regular driving as the atmosphere changes.

No problem on the help man.

 

I use the techedge wideband connected to my 1052

Nice display on it as well.

 

innovate and plx are both good and can output a 0-5V signal to the AEM so you don't have to upgrade to the 1052U. the 1052U however does work much better than a piggyback and the O2 sensor warms up very fast compared to the other systems.

the other systems warm up so slow in comparison it makes tuning startup af ratios all but impossible. with the 1052U you'll be able to see af ratios almost instantly. other than that there's not a big difference except the 1052U is just simpler and less boxes to mount and wire up.
